Statewide Measure Cost Update

1
Statewide Measure Cost Update

• Overview Discussion

2
Background Purpose

• Background
• Measure cost studies provide the average
  incremental and full costs for new and retrofit
  energy efficiency measures (commercial and
  residential).
• Typically performed in concert with DEER energy
  savings estimates.
• Last update conducted in 2001.
• Purpose
• Create a common set of cost information and
  assumptions to be used as a starting point for
  all parties when planning and evaluating energy
  efficiency efforts.
• Consistency with DEER measure descriptions.

3
Measure List

• Initial measure lists will follow the DEER Update
  Study measure lists
• Residential retrofit - weather sensitive and
  non-weather sensitive.
• Non-residential retrofit - weather sensitive and
  non-weather sensitive.
• Initial attention should be given to measures
  likely to represent the bulk of savings from
  2006/7 program efforts
• Consultant will review 2004/5 measure activity
  for IOU and non-IOU programs.
• Consultant will suggest other measures for
  initial attention based upon impact of new
  standards upon likely program offerings.
• CFLs (screw-in and modular), programmable
  thermostats, package and split system air
  conditioners, T-8 and T-5 lighting systems,
  clothes washers, dishwashers, pool pumps, and
  dual pane windows will be among the first
  measures examined.

Issues For Discussion

• Should focus/scope be broadened beyond
  residential and commercial retrofit measures?
• Industrial?
• Commercial new construction?
• Residential new construction?
• Should installation costs be estimated for each
  measure or for a subset of measures?
• Direct install program support.
• More accurate cost comparison for individual
  measures with differing installation costs (e.g.,
  condensing furnaces and water heaters).
• Necessity of close linkage to DEER update
  efforts.
• Advisory group makeup/requirements.

5
Issues For Discussion (continued)

• Necessity of direct integration of measure cost
  information into DEER website.
• Might require website redesign.
• Updating issues (frequency timing).
• How should information from other EMV studies be
  integrated?
• Existing studies?
• Studies in process?
• Future studies?
• Should/can existing studies work scopes be
  modified to collect measure cost data for direct
  inclusion into the DEER/Measure cost database?
